Dear Vercel Support Team,
I am encountering a persistent "Element type is invalid: expected a string (for built-in components) or a class/function (for composite components) but got: undefined. You likely forgot to export your component from the file it's defined in, or you might have mixed up default and named imports." error when previewing the /admin/dashboard page in my Next.js project.
Project Context:
This is a Next.js project, specifically a fork of a v0 project (ID: driver-check-app).
Steps to Reproduce:
- Navigate to the
/admin/dashboard page.
- The error appears in the preview.
Recent Changes Made:
The error started occurring after making modifications to the app/admin/dashboard/page.tsx file. Specifically, I was:
- Reordering elements on the dashboard.
- Changing a "History" tab to a text link ("スタッフ提出状況確認") that points to
/admin/drivers.
- Removing the
TabsContent block associated with the previously existing "History" tab.
Troubleshooting Steps Taken:
I have attempted to resolve this by:
- Reviewing
app/admin/dashboard/page.tsx for incorrect imports or undefined components.
- Ensuring all
shadcn/ui components (like Card, Tabs, Progress) are correctly imported and used.
- Re-exporting the
components/ui/tabs.tsx file to ensure it's properly recognized by the environment.
Despite these efforts, the error persists. It seems to indicate an issue with a component not being correctly recognized or exported, but the code appears correct on my end.
Could you please assist me in diagnosing and resolving this issue? Any insights into potential causes or further debugging steps would be greatly appreciated.
Thank you for your time and support.
Best regards,
[あなたの名前]
